Road Opening and Closing Dates
(See plowing updates during spring road opening.)
Clearing of the Tioga Road begins on or about April 15 each year and usually takes between one and two months. Predicting when these roads will open is not possible, even in late spring, because weather in April and May can affect plowing progress significantly.
